Hi Edmund,

I have done this now the same way I addressed this issue in its
dependency package, genometools:

MACHINE:=$(shell uname -m)
ifeq ($(m64),yes)
  ifeq (,$(filter $(MACHINE),arm64 ia64 alpha mips64 mips64el aarch64))
    CFLAGS += -m64
  endif
endif

Basically, these archs won't get -m64. I have uploaded a new version and
let's see if it builds now.

Cheers
Sascha
